until his death in a car accident in Australia in 1997. Gene was involved in the Lunar Ranger and Surveyor programs and continued with the crewed Apollo programs. He culminated his lunar studies in 1994 with new data on the Moon from Project Clementine, for which he was the science-team leader. Gene collaborated closely with his wife,

, a planetary astronomer. The discovery of Comet Shoemaker-Levy (which impacted Jupiter in 1994) with colleague David Levy, gained them worldwide fame. This was just one of Gene's many great accomplishments. Starting in 1963, the Astrogeology Science Center played an important role in training astronauts destined to explore the lunar surface and in supporting the testing of equipment for both crewed and uncrewed missions. As part of the astronauts' training, USGS and NASA geoscientists gave lectures and field trips during the 1960s and early 1970s to teach astronauts the basics of terrestrial and lunar geology. Field trips included excursions into the Grand Canyon to demonstrate the development of geologic structure over time;

cinder cone and nearby lava flows in the Flagstaff area. This training was essential to giving astronauts the skills and understanding to make observations about what they would see on the lunar surface and to collect samples for later study back on Earth. The volcanic fields around Flagstaff have proven particularly useful in testing equipment and training astronauts. Cameras planned for use in the Surveyor project were tested on the Bonito Flow in Sunset Crater National Park because the lava flow appeared to be similar to flows on the lunar surface. A field of artificial impact craters was created in the Cinder Lakes volcanic field near Flagstaff to create a surface similar to the proposed first crewed American landing site on the Moon. Jack Schmitt joined the Astrogeology team as a geologist at the Flagstaff Science Center in 1964, having recently earned a doctorate degree from Harvard University. In addition to assisting in the geologic mapping of the Moon, he led the Lunar Field Geological Methods project. When NASA announced a special recruitment for scientist-astronauts in late 1964, Schmitt applied. Out of more than 1,000 applicants, six were chosen. Of those six, Joe Kerwin, Owen Garriott, and Edward Gibson would fly in the Skylab missions in 1973 and 1974, and Schmitt would go to the Moon on the Apollo 17 mission.

Astrogeology today

Today, the mission of the USGS Astrogeology Science Center is to serve the nation, the international planetary science community, and the general public's pursuit of new knowledge of the Solar System by : * Conducting innovative, fundamental research that advances the fields of planetary cartography, geoscience, and remote sensing. * Developing state-of-the-art software and techniques for the scientific and cartographic analysis of planetary remote sensing data. * Participating in the collaborative planning and operation of space exploration missions. * Producing accurate cartographic products, recognized internationally as benchmarks. * Establishing data archive and mapping standards that foster international consistency. * Archiving and distributing data and products for efficient access through modern technology. The USGS Astrogeology Science Center participates in all phases of spaceflight missions across the Solar System. This includes providing scientific input for mission planning, creating foundational geospatial data products, supplying landing site maps and characterization, tactical operations of rovers and orbiters, and assuring the long-term accessibility of the data returned from these missions. Historic, recent, ongoing, and upcoming space missions involving the USGS Astrogeology Research Program include: *
